comment How can I take wide angle macro photos with a Nikon APS-C camera?
Thanks for your response. It wasn't clear to me how to determine when an extension tube is too thick to prevent any sort of focusing. With a wide angle lens, the focal length is always shorter than the flange distance, and they have to use something like a retrofocal design. So a thin lens model won't help in figuring out what would happen. I should have though of the obvious solution: just hold the lens in front of the camera without mounting it to test whether an extension tube of a certain thickness would work.

Anyone voting to close, please read the question carefully first. I thought it was clear that I'm asking for facts on what works, not opinions on what's best. If the question is not clear, please comment.

This is not a recommendation question. I'm not asking what's the best. I'm asking what works at all (based on first hand experience).

comment Why does L*=0 not correspond to black in the L*a*b* color space?
Maybe easier to see: Manipulate[ ArrayPlot@ Table[LABColor[l, a, b], {a, -1, 1, .05}, {b, -1, 1, .05}], {{l, 0}, -1, 2} ]

comment Why do digital cameras not have an iso rating?
I don't think people will stop and spend time to convince you about this, I certainly won't. However, you could easily do some research using Google to find out for yourself. You might want to read up on Poisson process and shot noise too.

comment Why do digital cameras not have an iso rating?
Digital cameras have an ISO setting. Sensitivity is variable and the maximum ISO is always clearly indicated in the specifications. There's a tradeoff when you increase sensitivity: the picture will have more noise. This is one reason why they don't have the sensitivity fixed at a permanent high value. Also see here cambridgeincolour.com/tutorials/camera-exposure.htm and here cambridgeincolour.com/tutorials/image-noise.htm

comment How does software that extracts or views EXIF work?
Also, many of those tools are open-source, meaning you're free to inspect how they work.

comment What's the easiest way to access pure raw data (without demosaicing)?
I was just warning you: it's standard practice on SE to note if you're the developer, especially if it's not a free program. Otherwise someone might flag it as spam. (I won't do that, but since you're new here I thought it's fair to mention it.)

It's not free any more though, unfortunately, but it was a nice program when I tried it. It didn't seem to do anything more than dcraw though, other than adding a GUI. Are you one of the devs? If yes, you should make that clear in this post.
